Description

Technical Field

[0001] This utility model relates to the field of residual pressure controller technology, specifically a residual pressure controller with multiple signal outputs. Background Technology

[0002] Overpressure controllers are a key device in building HVAC systems, especially smoke control systems, and are mainly used to control the pressure difference between a specific area and other adjacent areas during a fire.

[0003] For example, patent application number 202123420882.1 published on the China Patent Network, entitled "A Residual Pressure Controller," describes a base housing with a track slot and clips at the bottom. The heat sink assembly includes a heat sink, heat pipes, and chip heat-conducting sheets. Multiple chip heat-conducting sheets are mounted on the heat-absorbing section of the heat pipes. The heat-dissipating section of the heat pipes is connected to one side of the heat sink. The heat sink is positioned within the track slot of the base housing, with the heat pipes facing upwards. A layer of graphite paper heat-conducting layer is adhered to the other side of the heat sink without the heat pipes. The heat pipes are bent to accommodate the chip positions on the circuit board. The chip heat-conducting sheets are attached to the chips requiring heat dissipation. The circuit board is located inside the base housing, with the chips requiring heat dissipation facing downwards. The upper shell is fastened to the base housing, surrounding the circuit board. This invention adds a heat-conducting sheet assembly to the housing to accelerate internal heat dissipation and ensure the normal operation of the residual pressure controller.

[0004] However, existing overpressure controllers require connection to a large number of cables. Each cable needs to be fixed by independent plugging and using threaded components. Connecting a large number of cables is time-consuming and labor-intensive, affecting the installation and maintenance efficiency of the overpressure controller.

[0005] Therefore, it is necessary to redesign and modify the residual pressure controller with multiple signal outputs. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a residual pressure controller with multiple signal outputs, which has the advantages of easy disassembly and maintenance. It solves the problem that existing residual pressure controllers require connection to a large number of cables, each of which needs to be fixed by independent plugging and using threaded components. The connection of a large number of cables is time-consuming and laborious, affecting the installation and maintenance efficiency of the residual pressure controller.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a residual pressure controller with multiple signal outputs, comprising a body;

[0008] Cables located on the top of the machine body;

[0009] The bottom end of the cable extends into the interior of the machine body connection end and is electrically connected to the machine body. A first positioning frame is provided on the top of the machine body on the back of the cable, and a second positioning frame is provided on the top of the machine body on the front of the cable. The first positioning frame and the second positioning frame are attached to each other and squeeze and fix the cable. A transmission frame is provided on the surface of the machine body, and the transmission frame can carry the first positioning frame and the second positioning frame vertically up and down.

[0010] As a preferred embodiment of this utility model, a bracket is fixedly connected to the rear side of the top of the transmission frame, and the side of the bracket away from the transmission frame extends to the back of the first positioning frame and is fixedly connected to the first positioning frame. The two sides of the bracket are connected to the second positioning frame through a connecting structure. An adjustment structure is provided at the bottom of the machine body, and the adjustment structure can control the vertical lifting and lowering of the transmission frame.

[0011] In a preferred embodiment of this invention, the adjustment structure includes a screw movably connected to the bottom of the machine body via a bearing. The bottom end of the screw passes through the transmission frame and extends to the bottom of the transmission frame. The transmission frame and the screw are threadedly connected, and a rotating wheel is fixedly connected to the bottom end of the screw.

[0012] As a preferred embodiment of this utility model, a support plate is fixedly connected to the bottom of the machine body. The side of the support plate away from the machine body is sleeved on the surface of the screw and located at the bottom of the transmission frame. The support plate and the screw are movably connected by a bearing.

[0013] As a preferred embodiment of this utility model, the connecting structure includes connecting blocks fixedly connected to both sides of the top of the transmission frame. A swing rod is movably connected to the side of the connecting block away from the transmission frame via a pin. The side of the swing rod away from the connecting block extends to the front of the second positioning frame and is fixedly connected to the second positioning frame. The second positioning frame can change the extrusion pressure by swinging.

[0014] As a preferred embodiment of this utility model, a fork is fixedly connected to the side of the swing arm near the connecting block, and movable blocks are fixedly connected to both sides of the front of the machine body. A slide rod located inside the fork is fixedly connected to the outer side of the movable block. The slide rod is slidably connected to the fork, and the slide rod can control the swing of the fork when the fork moves vertically with the connecting block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model solves the problem of unstable insertion by integrating cable fixing and pushing functions. At the same time, the clamping effect of the first positioning frame and the second positioning frame provides a stable fixing effect, preventing the cable from loosening or shifting in subsequent operations. The transmission frame design enables the entire clamping mechanism to rise and fall vertically, ensuring that the clamped cable is smoothly pushed into the machine body connection end along the predetermined direction, accurately deepening the insertion depth.

[0017] 2. This utility model directly connects the transmission frame and the first positioning frame through a bracket, ensuring that the first positioning frame can rise and fall precisely and synchronously with the transmission frame. The connecting structure associates the second positioning frame with the bracket, ensuring that the second positioning frame holding the cable can also participate in the overall lifting and pushing action after being fixed.

[0018] 3. This utility model controls the vertical lifting and lowering of the transmission frame by setting a screw. It can utilize the good self-locking property of the threaded engagement to automatically maintain the current position when no external force is applied, preventing the clamping mechanism from sliding down or loosening due to vibration or its own weight.

[0019] 4. This utility model provides an additional support point for the screw located below the transmission frame through a support plate, and is connected by a bearing, which can effectively limit the radial swing and vibration of the screw and ensure the concentricity and stability of the screw rotation.

[0020] 5. By introducing a swing arm, the second positioning frame is no longer rigidly following the lifting and lowering, but has a swinging degree of freedom, allowing the second positioning frame to slightly and adaptively adjust its posture according to changes in cable size or assembly tolerance during the lifting and lowering process.

[0021] 6. This utility model, by setting up a shift fork and a slide bar, can convert the vertical lifting motion of the transmission frame into the swinging motion of the shift fork. When the transmission frame moves vertically, the sliding trajectory of the slide bar inside the shift fork forces the shift fork to rotate around its pivot point, ensuring that the second positioning frame passively changes its angle as the lifting height changes.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 4 As shown, the present invention provides a residual pressure controller with multiple signal outputs, including a body 1;

[0029] Cable 2 is located at the top of the body 1;

[0030] The bottom end of the cable 2 extends into the interior of the connecting end of the body 1 and is electrically connected to the body 1. The top of the body 1 is provided with a first positioning frame 3 located on the back of the cable 2, and the top of the body 1 is provided with a second positioning frame 4 located on the front of the cable 2. The first positioning frame 3 and the second positioning frame 4 are attached to each other and squeeze and fix the cable 2. The surface of the body 1 is provided with a transmission frame 5, which can carry the first positioning frame 3 and the second positioning frame 4 vertically up and down.

[0031] refer to Figure 2 A bracket 6 is fixedly connected to the rear side of the top of the transmission frame 5. The side of the bracket 6 away from the transmission frame 5 extends to the back of the first positioning frame 3 and is fixedly connected to the first positioning frame 3. The two sides of the bracket 6 are connected to the second positioning frame 4 through a connecting structure. An adjustment structure 7 is provided at the bottom of the machine body 1. The adjustment structure 7 can control the vertical lifting of the transmission frame 5.

[0032] As a technical optimization of this utility model, the transmission frame 5 and the first positioning frame 3 are directly connected by the bracket 6, ensuring that the first positioning frame 3 can rise and fall precisely and synchronously with the transmission frame 5. The connection structure associates the second positioning frame 4 with the bracket 6, ensuring that the second positioning frame 4 holding the cable 2 can also participate in the overall lifting and pushing action after being fixed.

[0033] refer to Figure 2 The adjusting structure 7 includes a screw 8 movably connected to the bottom of the body 1 via a bearing. The bottom end of the screw 8 passes through the transmission frame 5 and extends to the bottom of the transmission frame 5. The transmission frame 5 and the screw 8 are threadedly connected. A rotating wheel 9 is fixedly connected to the bottom end of the screw 8.

[0034] As a technical optimization of this utility model, by setting the screw 8 to control the vertical lifting of the transmission frame 5, the good self-locking property of the threaded engagement itself can be utilized to automatically maintain the current position without applying external force, preventing the clamping mechanism from sliding down or loosening due to vibration or its own weight.

[0035] refer to Figure 2A support plate 10 is fixedly connected to the bottom of the machine body 1. The side of the support plate 10 away from the machine body 1 is sleeved on the surface of the screw 8 and located at the bottom of the transmission frame 5. The support plate 10 and the screw 8 are movably connected by bearings.

[0036] As a technical optimization of this utility model, the support plate 10 provides an additional support point for the screw 8 located below the transmission frame 5, and is connected by a bearing, which can effectively limit the radial swing and vibration of the screw 8 and ensure the concentricity and stability of the screw 8 rotation.

[0037] refer to Figure 4 The connecting structure includes connecting blocks 11 fixedly connected to both sides of the top of the transmission frame 5. A rocker arm 12 is movably connected to the side of the connecting block 11 away from the transmission frame 5 via a pin. The side of the rocker arm 12 away from the connecting block 11 extends to the front of the second positioning frame 4 and is fixedly connected to the second positioning frame 4. The second positioning frame 4 can change the extrusion pressure by swinging.

[0038] As a technical optimization of this utility model, the introduction of the swing arm 12 makes the second positioning frame 4 no longer rigidly follow the lifting and lowering, but has a swinging degree of freedom, allowing the second positioning frame 4 to slightly adaptively adjust its posture according to the changes in the size of the cable 2 or the assembly tolerance during the lifting and lowering process.

[0039] refer to Figure 4 A fork 13 is fixedly connected to the side of the swing arm 12 near the connecting block 11. Movable blocks 14 are fixedly connected to both sides of the front of the body 1. A slide rod 15 located inside the fork 13 is fixedly connected to the outside of the movable block 14. The slide rod 15 is slidably connected to the fork 13. The slide rod 15 can control the swing of the fork 13 when the fork 13 moves vertically with the connecting block 11.

[0040] As a technical optimization of this utility model, by setting the shift fork 13 and the slide bar 15, the vertical lifting motion of the transmission frame 5 can be converted into the swinging motion of the shift fork 13. When the transmission frame 5 moves vertically, the sliding trajectory of the slide bar 15 inside the shift fork 13 forces the shift fork 13 to rotate around its pivot point, ensuring that the second positioning frame 4 will passively change its angle as the lifting height changes.

[0041] The working principle and usage process of this utility model: The operator places cable 2 on the top of the machine body 1, with its bottom end extending into the interior of the connecting end of the machine body 1 for electrical connection. At this time, cable 2 is in an unfixed state. Next, the operator rotates the rotating wheel 9 located at the bottom of the machine body 1, driving the screw 8 to rotate. When the screw 8 rotates, the transmission frame 5 moves vertically downwards. The lifting and lowering of the transmission frame 5 drives the first positioning frame 3 and the second positioning frame 4 to move together. The transmission frame 5 is fixedly connected to the first positioning frame 3 through the bracket 6 on its rear side, ensuring that the first positioning frame 3 directly follows the vertical movement of the transmission frame 5. At the same time, the connecting blocks 11 on both sides of the top of the transmission frame 5... The swing arm 12, which is movably connected by a pin, transmits motion to the second positioning frame 4. During the movement of the second positioning frame 4, the fork 13 on the swing arm 12 forms a sliding engagement with the slide rod 15 fixed on the front of the machine body 1. When the transmission frame 5 moves vertically, the slide rod 15 forces the fork 13 to swing, thereby adjusting the angle of the second positioning frame 4, thus dynamically maintaining or changing the squeezing pressure on the cable 2, ensuring that the cable 2 is subjected to uniform force during the pushing process. Finally, the downward movement of the transmission frame 5 pushes the entire clamping structure downward, causing the fixed cable 2 to move deeper into the connection end of the machine body 1, thereby achieving the effect of improving the connection strength between the cable 2 and the machine body 1.

[0042] In summary, this overpressure controller with multiple signal outputs solves the problem of unstable insertion by integrating the fixing and pushing functions of cable 2. At the same time, the clamping action of the first positioning frame 3 and the second positioning frame 4 provides a stable fixing effect, preventing cable 2 from loosening or shifting in subsequent operations. The design of the transmission frame 5 enables the entire clamping mechanism to rise and fall vertically, ensuring that the clamped cable 2 is smoothly pushed into the connection end of the machine body 1 in a predetermined direction, accurately deepening the insertion depth.
